Iyo abarwayi bazanye ingingo yibibara byamabara, ikintu cya mbere kiza mubitekerezo ni uguhindura ibara ryamaso. Usibye impamvu zo kwisiga, lisiti yo guhuza ibara cyangwa irangi irashobora gufasha abarwayi muburyo butandukanye, nko kugabanya urumuri cyangwa guhindura ibara imyumvire mubantu bafite ubumuga bwo kutabona.
Haba kubikoresha kwisiga cyangwa kuvura, linzira yo guhuza ibara muri rusange ntabwo aribyo OD bivuga abarwayi.Nyamara, iyo bimaze gusabwa, birashimishije abarwayi benshi.
guhuza ibara
Ibyifuzo birashobora gutangwa muburyo butandukanye. Hatitawe ku kuntu byatanzwe, ni ngombwa kumenya ko nubwo linzira zifite amabara zishobora kugirira akamaro abarwayi, zitwara ibyago benshi batazi. Reka dusuzume uburyo utuntu duto two guhuza amabara dushobora kugirira akamaro abarwayi neza kandi neza.
Amashanyarazi yakozwe namabara menshi yamashanyarazi arashobora kuboneka mubikoresho byo kugerageza kandi bigatangwa muburyo bwibiro. Nyuma, aya masasu yakozwe na mudasobwa. Kubwibyo, OD ntishobora guhindura ibipimo nko kwiyuzuzamo, umucyo, cyangwa guhuza amabara.
Amashanyarazi yakozwe namabara menshi arashobora kongera ibara risanzwe ryijisho ryumurwayi cyangwa kuyihindura rwose.Birasa ninzira zoroshye zo guhuza zikoreshwa mugukosora amakosa yangiritse.Niyo mpamvu, ntamwanya wongeyeho wo kwicara usabwa ugereranije nubushakashatsi bwakozwe neza. lens.
Ibyinshi mubyakozwe namabara menshi afite imbaraga zumubumbe zisimburwa burimunsi cyangwa ukwezi.Ibikoresho ntibihendutse kubera umusaruro mwinshi, kuburyo bishobora kumenyekana byoroshye kubarwayi nkuburyo bwigihe cyose cyangwa bwigihe gito.
Ibikoresho byinshi byakozwe muburyo bwo guhuza ibara bikunzwe cyane mubirori mbonezamubano.1 Bitewe no gushyigikirwa kwabo mucyo hamwe nibibara byamabara bikikije iris, byemerera uburyo butandukanye bushobora gukora ibintu bisanzwe cyangwa bitinyutse.
Kurugero, umurwayi ufite amaso yumukara arashobora guhitamo igikara cyangwa hazel kugirango ahindure gato ibara rya iris, cyangwa ubururu cyangwa icyatsi kugirango ahindure isura kuburyo butangaje.Nubwo byoroshye guhuza no kwigisha abarwayi kubyo bahisemo, izo lens zifite hejuru cyane igipimo cyingorabahizi mubantu bambara lens.2
Ingorane Mugihe ibyago byo kwisiga bigaragarira kuri OD babonye ingaruka za ocular, abaturage muri rusange usanga batamenyereye iterabwoba ryangiza ubuzima bwamaso.Iyo Berenson nabandi.yakoze ubushakashatsi ku bumenyi bw'abarwayi no gukoresha uburyo bwo kwisiga bwo kwisiga, ibisubizo byagaragaje ko abarwayi benshi batumva ingaruka ndetse n'amabwiriza akoreshwa neza.3,4 Nk’uko ubushakashatsi bwabigaragaje, umwe mu barwayi bane yavuze ko yakoresheje lensike yo kwisiga mbere, kandi benshi babonye lens. biturutse ahantu hatabifitiye uburenganzira.
Tumubajije ibijyanye nubumenyi bwitumanaho, ibisubizo byerekanaga ko abarwayi benshi batazi kwambara protocole ikwiye.3 Abarwayi benshi ntibazi ko bitemewe kugurisha lensisiti zandikirwa kuri konti nta nyandiko yandikiwe mugihugu hose.Ntabwo bamenya ko umubonano lens ntabwo ari panacea, ko parasite ishobora kwizirika kumurongo, kandi ko "anime" lens ntabwo byemewe na FDA.3.
BIFITANYE ISANO: Ibisubizo by'amatora: Niki Utishimiye cyane Kwambara Lens Wambara? Mu barwayi babajijwe, 62.3% bavuze ko batigeze bigishwa uburyo bwo guhanagura lens.3
Mugihe dushobora kuba tuzi bimwe mubyavuye mubushakashatsi, ni ngombwa gusuzuma uburyo lensike yo kwisiga yongerera amahirwe ibintu bibi (AEs) ugereranije ninzira zifatika.
AEs Ibara ryerekana amabara afite ibyago byinshi byo kwandura no gutwika bitewe nuburinganire bwabyo.Ubushakashatsi buherutse gukorwa bwasuzumye uburyo butandukanye bwo kwisiga bwo kwisiga kugirango hamenyekane aho pigment ziri murwego rwa lens.5 Yasanze ibyinshi byasesenguwe birimo byinshi muri pigment muri mm 0.4 z'ubuso.Ibihugu byinshi ntibigenzura urugero rw'uruzitiro, ariko ahantu birashobora kugira ingaruka kumutekano no guhumurizwa.5.
Ubundi bushakashatsi bwerekanye ko ibirango byinshi byandikirwa byananiranye ikizamini cya rub-off, bigatuma ibara ryamabara rivaho.6 Ihanagura ikizamini Koresha ipamba kugirango uhanagure buhoro buhoro imbere ninyuma yibice byitumanaho mumasegonda 20, hanyuma upime umubare ya pigment.
Bifitanye isano: Lens hamwe na OCT yagenwe na scleral-lens umwanya wananiwe kwipimisha kwerekanaga kwinshi kwa Pseudomonas aeruginosa, byaviriyemo kwiyongera kwa AEs hamwe na AE ibangamira iyerekwa.Iyi pigment wasangaga irimo ibintu bifite ubumara bwumubiri wa ocular.7.
Kuba hari pigment iyo ari yo yose irashobora gutera AE.Lau et al yasanze lens ifite pigment hejuru yinteguza (imbere cyangwa inyuma) yari ifite agaciro gakomeye ko guterana mubice byamabara kuruta ahantu hasobanutse.8 Ubushakashatsi bwanzuye ko lisiti yo kwisiga hamwe na pigment igaragara ifite ubuso budahwitse, bikavamo amavuta no kwiyongera kwubuso bwubutaka.Amavuta nubusembwa bigira uruhare runini mukubungabunga firime ya marira.Nkigisubizo, guhagarika umutima bishobora gutuma umuntu atabona neza kandi bikagabanya ihumure ryitumanaho.
Acanthamoeba keratitis irashobora kubaho hamwe nubwoko bwose bwo guhuza amakuru, ibyago tuganira nabambaye imyenda mishya.Kwigisha abarwayi kwirinda gukoresha amazi afite lensitike yoroshye ni ikintu cyingenzi cyamahugurwa yo kwinjiza no gukuraho.Ibisubizo byinshi hamwe na hydrogen peroxide ibisubizo birashobora gufasha gabanya AEs ifitanye isano na mikorobe, ariko ubushakashatsi buherutse gukorwa bwerekanye ko ibice bigize lens bigira ingaruka ku kuba Acanthamoeba ifata lens.9
Bifitanye isano: Tanga Toric Orthokeratology Lens Scanning Electron Microscopy Amashusho Ukoresheje amashusho ya SEM, Lee nibindi.wasanze ubuso bwa acromatique bwo kwisiga bwo kwisiga bworoheje kandi buringaniye kuruta amabara.
guhuza ibara
Basanze kandi umubare munini wa Acanthamoeba trophozoite wafatanyaga ahantu habi cyane ugereranije n’ibara ritagira ibara, ryoroshye.
Mugihe ibyifuzo byo kwisiga byo kwisiga byiyongera, iyi ningaruka igomba kuganirwaho nabarwayi bambara lens.
Hamwe nibikoresho bishya bya lens, nka hydrogène ya silicone, ibyuma byinshi byandikirwa hamwe bitanga uburyo bwinshi bwo kwinjiza ogisijeni kuruta ibikenewe. Ikwirakwizwa rya ogisijeni ripimirwa muri zone optique yo hagati ya lens, mugihe kwanduza ogisijeni ya periferique ari ikibazo.
Ubushakashatsi bwakozwe na Galas na Umuringa bwakoresheje lens idasanzwe yakozwe gusa na pigment binyuze muri zone optique yo hagati kugirango bapime umwuka wa ogisijeni binyuze muri pigment.10 Basanze ko pigment itagize ingaruka ku mibare ya ogisijeni, bityo bikerekana ko itagabanya cyangwa ngo ihindure lens umutekano. BIFITANYE ISANO: Impuguke zitanga amabanga yo guhuza Lens Imyitozo Intsinzi
UMWanzuro fasha kugabanya ibintu bibi no kunoza umutekano wibara ryitumanaho.
